▎ 摘　　要

This paper reports a mechanically flexible, transparent thin film transistor that uses graphene as a conducting electrode and single-walled carbon nanotubes (SWNTs) as a semiconducting channel. These SWNTs and graphene films were printed on flexible plastic substrates using a printing method. The resulting devices exhibited a mobility of similar to 2 cm(2) V(-1) s(-1), On/Off ratio of similar to 10(2), transmittance of similar to 81% and excellent mechanical bendability.
